BACKGROUND OF THE INVENTION

This invention relates to oral health care implements and systems,particularly relating to improved toothbrushes utilizing newtechnologies for the dental field. In particular, the invention relatesto the usage-monitoring capabilities of both manual and electrictoothbrushes.

The human body, including the oral cavity, possesses the property ofbeing a good capacitor, such that the human body has a detectablecapacitance. The capacitance of the human body is significant enough toaffect changes in an electrical circuit with capacitance. Thecapacitance of the human body can affect the overall capacitance of anelectrical circuit when introduced via a conductive material.

Dental plaque is a biofilm that forms naturally on teeth betweenbrushing and dental visits. Dental plaque can be a precursor to moresevere oral health problems including: dental caries, tooth decay,gingivitis, and chronic periodontitis. The occurrence of dental cariesis one of the largest health epidemics in the world and is the mostcommon chronic childhood disease in the United States. Likewise,gingivitis and dental calculus are two of the most common systemicdiseases of the body. It is desirable to monitor and diagnose dentalplaque early stage as a preventive measure against more serious diseasestates. The most common preventive measure implemented to control theformation of dental plaque is the toothbrush.

Further still, clinical dental visits with dental practitioners are amethod of prevention and detection of dental plaque. Regular dentalvisits are recommended to occur every six months. Regular toothbrushreplacement is recommended to occur every three months according todental practitioners. The lack of adherence to these recommendations andlack of brushing compliance is often a contributing factor to thedevelopment of dental plaque and its associated complications. Regularreplacement of toothbrushes is often disregarded by users and causeissues as bristles become deformed and are no longer providing theproper cleaning.

Consequently, dental practitioners are in need of an adequate means tomonitor the usage of dental implements between clinical dental visits.Moreover, dental practitioners are in need of an accurate method ofdetermining the usage of a particular dental implement to makerecommendations based upon its usage. Usage monitoring of dentalimplements has long been difficult as the main method of collecting datais by inquiring a particular patient. Consequently, a method formeasuring the usage of dental implements is desirable for dentalpractitioners.

DETAILED DESCRIPTION OF THE INVENTION

The oral health care implement and system with proximity sensor isencompassed in a plurality of preferred embodiments that shall bediscussed in the present section.

A plurality of embodiments comprise an oral health care implement. Insome embodiments, the oral health care implement is operated in the oralcavity of a human being characterized as the first portion of thealimentary canal that receives food and saliva, and containing a mucousmembrane epithelium lining referred to as the oral mucosa. The oralcavity is further characterized as having alveolar arches typicallycontaining teeth, which are either natural, synthetic, or a combinationthereof, and used primarily for the preparatory chewing of food fordigestion. The implement, in this embodiment, is capable of beingoperated within the oral cavity, wherein the implement is capable ofbeing operated in a high moisture environment and is manufactured frombio-compatible materials approved for use in the oral cavity.

In some embodiments, the oral health care implement comprises a handlecharacterized by three general sections, which are a distal end 14, amiddle portion, and a proximal end 19. The distal end 14 of the handleis regarded as the end of the handle that is the extreme end away fromthe user's primary point-of-contact with the handle, which, in someembodiments, is the extreme end away from the user's hand. The distalend 14, in some embodiments, is further characterized as the end of thehandle that is most prominently utilized in the implement's workingarea, which is the oral cavity in a plurality of embodiments. Theproximal end 19 of the handle is characterized as the end of the handlethat is closest to the user's primary point-of-contact, which, in someembodiments, is the user's point-of-contact with the handle. The middleportion of the handle is characterized as the portion of the handlecentrally located between the distal end 14 and the proximal end 19 ofthe handle.

In some further embodiments, the oral health care implement is atoothbrush 10. A toothbrush 10 is an oral health care implement used forthe cleaning of teeth and gingiva, more commonly referred to as gums. Atoothbrush 10 comprises a brush head consisting of a plurality ofbristles 25 arranged into compact clusters, often referred to as tufts,mounted onto the brush head. Accordingly, the tufts are often mounted inan intentional pattern to facilitate cleaning of teeth and gums. Atoothbrush 10 further comprises a handle that includes the brush headand extends proximally from the brush head, which is used for graspingand movement of the toothbrush 10. The handle, consequently, has adistal end 14 and a proximal end 19. The distal end 14 of a toothbrush10 handle, in some embodiments, is the brush head of the toothbrush 10where said bristles 25 reside. The proximal end 19 of a toothbrush 10handle, in some embodiments, is the extreme opposite end from the brushhead where the user grasps the handle. In some embodiments, the bristles25 are manufactured from either a natural material, synthetic material,or a combination thereof. One example of a natural material is animalhair. An example of a typical synthetic material used in toothbrushbristles is Nylon.

In some further embodiments, the oral health care implement is aflosser. A flosser is an oral health care implement used for the removalof food and dental plaque from teeth, especially between teeth and otherplaces a toothbrush cannot effectively clean. A flosser comprises aflosser head having two parallel protrusions with space between themsuch that a length of dental floss can be placed between the twoprotrusions. The dental floss is, most often, held taut by the twoprotrusions to facilitate proper cleaning. A flosser further comprises ahandle connected to the flosser head, which may be detachably connected.The handle has a distal end, middle portion, and proximal end such thatthe middle portion is contained between the distal end and proximal end.Two common orientations exist for the protrusions and the handleincluding F-shaped wherein the protrusions are generally perpendicularto the long axis of the handle; and the Y-shaped wherein the protrusionsare generally parallel to the long axis of the handle. The handle andprotrusions are most often manufactured from plastic. The dental flossis typically manufactured from either thin nylon filaments or plasticribbons. Further variations in dental floss include flavored orunflavored, and waxed or unwaxed.

In other further embodiments, the oral health care implement is a flosspick, which is an oral health care implement used for the removal offood and dental plaque from teeth. The floss pick shares many of thecharacteristics of the flosser with one major difference at the proximalend of the handle. The proximal end of the handle of the flosser isprimarily used for grasping the implement. The proximal end of the flosspick is tapered into a point, much like the end of a toothpick, tofurther facilitate proper cleaning of teeth. Much like the flosser, thefloss pick protrusions also are largely oriented in either an F-shape orY-shape.

Further still, in some embodiments, the oral health care implement is agum massager. A gum massager is an oral health care implement used forthe stimulation of gums to promote better oral health. A gum massagercomprises a massager head shaped to facilitate effective stimulation ofgums. The massager head is often in the form of a rubber tip. A gummassager further comprises a handle with a distal end, middle portion,and proximal end. The handle is largely used for movement andmanipulation of the implement for proper use.

In some further embodiments, the oral health care implement is a tonguecleaner, which is used for cleaning bacteria, food debris, fungi, anddead cells from the surface of the tongue. A tongue cleaner comprises acleaning head on the distal end of a handle having a distal end, middleportion, and proximal end. The cleaning head often comprises a pluralityof small ridges oriented perpendicular to the long axis of the handle.The ridges are moved along the surface of the tongue to scrap offunwanted matter.

In some embodiments, the oral health care implement is an interdentalbrush used for cleaning between teeth. An interdental brush comprises abrush head that comprises the small brush sized to fit between a user'steeth. The brush head is located at the distal end of a handle, whereinthe handle has a distal end, middle portion, and proximal end. Aninterdental brush is also commonly referred to as an interproximal brushor a proxy brush.

Alternatively, the oral health care implement is a prophy cup used indental prophylaxis. A prophy cup is attached to the distal of end of thehandle and is often rubber. The prophy cup holds a certain amount ofabrasive polishing compound and typically is moved in a rotary motion tofacilitate cleaning.

Inherently, an implement has an associated motion when in use which ischaracterized as either manually driven or electromechanically driven. Amanually driven motion is regarded as a motion generated by the user byhis/her own power. Conversely, an electromechanically driven motion ischaracterized as a motion generated by electrical power which isconverted to mechanical power used to create the specifiedelectromechanically driven motion. In some embodiments, theelectromechanically driven motion is a side-to-side oscillating motionalso referred to as a vibratory motion. Often, the vibratory motion isgenerated by an electric motor with an eccentric weight on the driveshaft of the electric motor. In other instances, the vibratory motion isgenerated by an electrically conductive coil around the outside of amagnetic mass such that when an alternating current is applied to thecoil the magnetic mass oscillates causing vibration of the implement. Insome other embodiments, the electromechanically driven motion is arotation-oscillation motion wherein the brush head rotates eitherclockwise or counter-clockwise and then rotates in the oppositedirection of the first rotation. Electrical power is typically suppliedby a battery.

In some embodiments, the oral health care implement comprises aproximity sensor 90. In some embodiments, the proximity sensor 90 is acapacitive sensor. One type of capacitive sensor is a capacitive sensorthat works with a frequency change, alternatively referred to as afrequency change capacitive sensor. Optionally, another type ofcapacitive sensor is a capacitive sensor that works with a capacitivevoltage divider, alternatively referred to as a voltage dividercapacitive sensor. Both types of capacitive sensors detect the addedcapacitance of the oral cavity.

In some embodiments, the frequency change capacitive sensor comprises asensor surface 103, a resistor-capacitor (RC) circuit, and an RCoscillator, wherein the capacitance of the oral cavity introduced by thesensor surface 103 is a parallel capacitance in the RC circuit suchthat, when the capacitance of the oral cavity is present, the overallcapacitance of the RC circuit is altered. The RC oscillator operates ata set frequency controlled by the capacitance of the RC circuit. Thesensor surface 103 comes into proximity of the oral cavity, and,consequently, the capacitance of the oral cavity is introduced to the RCcircuit by a connection between the sensor surface 103 and the RCcircuit such that the capacitance of the oral cavity is a parallelcapacitance to the RC circuit. The change in overall capacitance of theRC circuit changes the frequency of the RC oscillator, thus, indicatingthe oral cavity is in proximity to the sensor surface 103.

In some embodiments, the frequency of the RC oscillator is compared to areference value to determine if a change in frequency occurs; therefore,the presence of the oral cavity is detected. Accordingly, threealternatives are presented for performing the comparison between thereference value and the frequency of the RC oscillator. One alternativeis to define the reference value as a frequency equivalent to theoperating frequency of the RC oscillator when the oral cavity is not inproximity to the sensor surface 103. In this instance, the referencevalue and the frequency of the RC oscillator are both input into afrequency comparator, wherein the frequency comparator evaluates if thevalues are similar; and thus, indicating one way or the other.

Optionally, the second alternative for comparison of the reference valueand the frequency of the RC oscillator comprises a frequency-to-voltageconverter, a DC voltage reference value, and a comparator, wherein thefrequency of the RC oscillator is input to the frequency-to-voltageconverter and a voltage corresponding to the frequency is output. Thecomparator compares the output voltage of the frequency-to-voltageconverter to the DC voltage reference value. The DC voltage referencevalue is equivalent to the output voltage of the frequency-to-voltageconverter when the oral cavity is not in proximity to the sensor surface103. Accordingly, the comparator outputs a signal consistent withwhether the DC voltage reference value is similar to the output of thefrequency-to-voltage converter.

Optionally, the third alternative for comparison of the reference valueand the frequency of the RC oscillator is to directly measure thefrequency of the signal by counting the number of rising or fallingedges in a defined time period utilizing a device similar to amicrocontroller. In this manner, a baseline operating frequency may beestablished, and any deviation in frequency beyond a defined thresholdwill indicate the oral cavity is in proximity to the sensor surface 103.

In some embodiments, the voltage divider capacitive sensor comprises asensor surface 103, which provides an analog input; a reference voltage;an analog-to-digital converter (A/DC); and a A/DC capacitor. The A/DC isinternally driven to the reference voltage such that the A/DC capacitoris fully charged, and the analog input of the sensor surface 103 isinternally grounded such that the sensor surface 103 is fullydischarged. Next, the analog input of the sensor surface 103 isinternally disconnected from the ground and is internally connected tothe A/DC such that the A/DC capacitor will discharge at least a portionof its charge to the sensor surface 103 in order to equal the voltagesof the sensor surface 103 and the A/DC capacitor. If the oral cavity isin proximity to the sensor surface 103, the sensor will appear to have alarger capacitance. Said larger capacitance results in a many timesmaller steady-state voltage between the A/DC capacitor and the sensoras compared to the condition when the sensor is in its normal, lowcapacitance state. The A/DC may measure the analog input and compare itto a threshold to determine if the sensor surface 103 is in proximity tothe oral cavity. The voltage provided to the A/DC will decrease in amanner indicative of the oral cavity's proximity to the sensor surface103. In some embodiments, the decrease in a manner indicative of theoral cavity's proximity to the sensor surface 103 is significant.

In some embodiments, the reference voltage, the A/DC, and the A/DCcapacitor are comprised in a microcontroller such that circuit comprisesa sensor surface 103 with an analog input connected to themicrocontroller. The A/DC of the microcontroller converts the voltageprovided to the A/DC from an analog signal to a digital signal. Themicrocontroller determines whether the sensor surface 103 is inproximity to the oral cavity based on the digital signal.

In some embodiments, the sensor surface 103 is a conductive material andcovered with an insulator material 97 such that the sensor surface 103can be embedded into the distal end 14 of the handle of the implement.Alternatively, in embodiments where the implement is a toothbrush 10,the sensor surface 103 may be embedded in the brush head or the neck ofthe toothbrush 10. The sensor surface 103 embedded in the brush head orthe neck of the toothbrush 10 would allow for proximity detection of theoral cavity when the toothbrush 10 was used for brushing a user's teeth,thus, providing information for when a toothbrush 10 is in use; or,alternatively, not in use.

In some embodiments, the insulator material 97 covering the sensorsurface 103 is the same material as the body of the implement. In someembodiments where the implement is a toothbrush 10, the insulatormaterial 97 covering the sensor surface 103 is the same material as thebody of the toothbrush 10 or the outer surface of the brush head.

An issue resides with the presence of water similarly producing acapacitance that may affect the sensor surface 103. A desirableadvancement of the present invention is to negate the issue of waterunwantedly providing a capacitance indicative of the oral cavity'sproximity to the sensor surface 103. In some embodiments, the negationof water is provided by an effective thickness of insulator material 97separating the water from the sensor surface 103. The insulator material97 allows detection of the sensor surface 103 in proximity to the oralcavity but does not allow detection of the sensor surface 103 inproximity to water. Alternatively, in some embodiments where theimplement is a toothbrush 10, the sensor surface 103 is functionallycoupled to the bristles 25 of the brush head such that the bristles actas an insulator material. In the same manner, the bristles 25 allowdetection of the sensor surface 103 in proximity to the oral cavity butdo not allow detection of the sensor surface 103 in proximity to water.

In some embodiments, the capacitance sensor may be constructed from twoparallel conductive plates separated by an insulator such that, in theactive portion of the sensor, the insulator allows for an air gapbetween the parallel plates. For example, the insulator comprises a holethat allows for an air gap between the parallel plates. Forces actingperpendicular to the plane of the parallel plates in the active regiondeform one conductor or both conductors. Accordingly, the parallelplates move closer together due to deformation, thus, increasing thecapacitance of the sensor. In some embodiments where the implement is atoothbrush 10, the bristles 25 comprised in the brush head areoperatively attached to at least one of the parallel plates, wherein theact of brushing may be detected by the force exerted by the bristles 25on the brush head. Thus, the act of brushing indicates the sensor is inproximity to the oral cavity.

In some embodiments, the proximity sensor 90 is a contact microphone,wherein the contact microphone detects vibration. The contact microphonedetects vibration created by the use of the implement in the oralcavity. In some embodiments, the contact microphone is in contact withat least a portion of the body of the implement, such that the createdvibrations are attenuated by the body of the implement. The vibrationsdetected by the contact microphone are compared to a reference thatcorrelates to the detection of the implement in the proximity of theoral cavity. If the detected vibrations match the reference value, thenthe implement is in proximity to the oral cavity.

In some embodiments, the contact microphone is substantially containedin a portion of the implement chosen from the distal end 14, the middleportion, the proximal end 19, and any combination thereof. In someembodiments, the contact microphone is chosen from the group condensermicrophone, electret condenser microphone, dynamic microphone, ribbonmicrophone, carbon microphone, piezoelectric microphone, fiber opticmicrophone, laser microphone, liquid microphone, microelectromechanicalsystem (MEMS) microphone, and any combination thereof.

Accordingly, a condenser microphone has a diaphragm that acts as oneplate of a capacitor and vibrations alter the distance between theplates of the capacitor. Two-types of condenser microphones existvarying in the method of extracting the audio signal. The first type isDC-biased, wherein the plates are biased with a fixed charge and thevoltage across the capacitor varies with variance in the capacitance dueto vibrations. The second type is radio frequency (RF), wherein a low RFvoltage is generated by a low-noise oscillator and the signal from theoscillator is amplitude modulated by the capacitance changes caused bythe sound waves moving the capsule diaphragm.

Similarly, an electret condenser microphone is consistent with acondenser microphone with one main difference being that the appliedcharge is provided by the permanent charge of an electret material. Anelectret material is a ferroelectric material that is permanentlyelectrically charged or polarized.

Alternatively, a dynamic microphone has a small, movable induction coilthat is located in the magnetic field of a permanent magnet, wherein theinduction coil is attached to the diaphragm. As the diaphragm vibrates,the induction coil moves about the magnetic field causing a varyingcurrent in the coil through electromagnetic induction.

Similarly, a ribbon microphone operates based on magnetic induction. Athin, often corrugated, metal ribbon is suspended in a magnetic fieldsuch that the metal ribbon is operably connected to the microphone'soutput. The vibration of the metal ribbon within the magnetic fieldgenerates the electrical signal.

A carbon microphone utilizes a capsule containing carbon granulespressed between two metal plates, one of which is the diaphragm thatvibrates in conjunction with sound waves. A voltage is applied acrossthe metal plates that causes current to flow through the carbongranules. As the diaphragm vibrates, varying pressure is applied to thecarbon granules, which causes them to deform and vary the contact areabetween each carbon granule. This variation changes the electricalresistance of the carbon granules, thus changing the current flowingthrough the microphone and causing the electrical signal.

Alternatively, a piezoelectric microphone utilizes the property ofpiezoelectricity exhibited by some materials. The vibrations arereceived by the piezoelectric material which translates the varyingvibrations into varying electrical signals. Piezoelectric microphonesare the most common type of contact microphone.

A fiber optic microphone operates by passing a laser source through thefiber optic that illuminates a reflective diaphragm. The diaphragmreceives sound vibrations, which varies the intensity of the reflectedlight. The modulated light then passes through a second fiber optic onto a photo detector, which transforms the light into an electricalsignal.

A laser microphone utilizes a laser beam aimed at a surface thatattenuates vibration. The vibrations of the surface change thereflection angle of the laser beam, which is detected and converted intoan electrical signal.

Alternatively, a liquid microphone comprises a metal cup filled withliquid and a diaphragm with a connected needle, such that vibrationscause the diaphragm to move up and down. Consequently, the needleoscillates in the water changing the electrical resistance between theneedle and the metal cup.

Lastly, a MEMS microphone utilizes a pressure-sensitive diaphragm etcheddirectly onto a silicon chip. The diaphragm is created by MEMSmanufacturing techniques. Most often, MEMS microphones operate in asimilar fashion to a condenser microphone.

In some embodiments, the proximity sensor 90 transmits at least onesignal indicative of proximity. Optionally, the proximity sensor 90transmits signals utilizing an electrically conductive wire, wherein theelectrical output of the proximity sensor 90 is input to theelectrically conductive wire and transmitted thereon. The electricaloutput of the proximity sensor 90 is, otherwise, referred to as thesignal indicative of proximity. The electrically conductive wire allowsfor the transmission of the signal indicative of condition.

In some embodiments, the oral health care implement further comprises adata processing unit 31 having at least one collector, a storage medium,and at least one processor, wherein the collector, storage medium, andprocessor, respectively, collect, store, and process data indicative ofproximity. Accordingly, in some embodiments, the data processing unit ischosen from the group microprocessor, microcontroller, fieldprogrammable gate array (FPGA), digital signal processing unit (DSP),application specific integrated circuit (ASIC), programmable logic, andcombinations thereof.

Additionally, in some embodiments, the collector of the data processingunit 31 is an electrically conductive wire, wherein the electricallyconductive wire receives the electrical output of the proximity sensor90, such that the electrical output of the proximity sensor 90 is atleast one signal indicative of proximity.

Moreover, in some embodiments, the storage medium of the data processingunit 31 is comprised of volatile memory and non-volatile memory, whereinvolatile memory is used for short-term storage and processing, andnon-volatile memory is used for long-term storage. Accordingly, in someembodiments, volatile memory is chosen from the group random-accessmemory (RAM), dynamic random-access memory (DRAM), double data ratesynchronous dynamic random-access memory (DDR SDRAM), staticrandom-access memory (SRAM), thyristor random-access memory (T-RAM),zero-capacitor random-access memory (Z-RAM), and twin transistorrandom-access memory (TTRAM). Optionally, in some embodiments,non-volatile memory is chosen from the group read-only memory (ROM),programmable read-only memory (PROM), erasable programmable read-onlymemory (EPROM), electrically erasable programmable read-only memory(EEPROM), flash memory, ferroelectric random-access memory (FeRAM),magnetoresistive random-access memory (MRAM), phase-change memory(PRAM), conductive-bridging random-access memory (CBRAM),silicon-oxide-nitride-oxide-silicon memory (SONOS), resistiverandom-access memory (RRAM), racetrack memory, nano-random-access memory(NRAM), and Millipede memory.

Further still, in some embodiments, the processor of the data processingunit 31 is chosen from the group microprocessor and microcontroller.

Optionally, in some embodiments, the oral health care implement furthercomprises at least one data extractor of data indicative of proximity inthe form of a signal, such that the data can be extracted to be used byanother medium. The signal can be extracted from the oral health careimplement via the data extractor, optionally, after being received bythe collector, the storage medium, or the processor, all of the dataprocessing unit. Optionally, the data extractor is chosen from the groupuniversal serial bus (USB), serial port, wired Ethernet port, radiofrequency, microwave communication, infrared short-range communication,near field communication, and short-range wireless communication viashort-wavelength ultra-high frequency radio waves also known as theregistered trademark Bluetooth®.

In some embodiments, the oral health care implement comprises a powersource 36 that distributes electrical energy to the electrically poweredcomponents of the oral health care implement including: the proximitysensor 103, the data processing unit 31, and other components defined asrequiring electrical power. Optionally, in some embodiments, the powersource 36 is a battery that is comprised of one or more electrochemicalcells that convert stored chemical energy into electrical energy, whichis then distributed to the remaining electrically powered components.Two primary types of batteries are utilized in some embodimentsincluding disposable batteries and rechargeable batteries. Both types ofbatteries come in various sizes and types.

Optionally, the power source of the oral health care implement is acable that temporarily connects the implement to electrical energy, thusdelivering electrical energy to the electrically powered components ofthe implement. In some embodiments, the electrical energy transferredthrough the cable is chosen from the group alternating current (AC) anddirect current (DC).

In some embodiments, the proximity sensor 90 and the data processingunit 31 operate in conjunction to determine and store the usageinstances and the usage time of the implement. Thus, the combination ofthe proximity sensor 90 and the data processing unit 31 provide a usagemonitor for the implement.

In some embodiments, the oral health care implement further comprises atleast one pressure sensor to determine if the pressure exerted on theimplement is excessive in relation to its intended use. In someembodiments, the pressure sensor may be constructed from two parallelconductive plates separated by an insulator such that, in the activeportion of the sensor, the insulator allows for an air gap between theparallel plates, referred to as a parallel plate capacitive sensor. Forexample, the insulator comprises a hole that allows for an air gapbetween the parallel plates. Forces acting perpendicular to the plane ofthe parallel plates in the active region deform one conductor or bothconductors. Accordingly, the parallel plates move closer together due todeformation, thus, increasing the capacitance of the sensor.

One type of pressure sensor is a parallel plate capacitive sensor thatworks with a frequency change, alternatively referred to as a frequencychange parallel plate capacitive sensor. Optionally, another type ofpressure sensor is a parallel plate capacitive sensor that works with acapacitive voltage divider, alternatively referred to as a voltagedivider parallel plate capacitive sensor. Both types of pressure sensorsdetect the added capacitance of the applied pressure of the oral cavity.

In some embodiments, the frequency change parallel plate capacitivesensor comprises at least two conductive sensor surfaces, anintermediary insulator, a resistor-capacitor (RC) circuit, and an RCoscillator, wherein the capacitance of the applied pressure introducedby the sensor surfaces is a parallel capacitance in the RC circuit suchthat, when the capacitance of the applied pressure is present, theoverall capacitance of the RC circuit is altered. The RC oscillatoroperates at a set frequency controlled by the capacitance of the RCcircuit. The sensor surfaces deform due to applied pressure, and,consequently, the capacitance of the deformation due to applied pressureis introduced to the RC circuit by a connection between the sensorsurfaces and the RC circuit such that the capacitance of the appliedpressure is a parallel capacitance to the RC circuit. The change inoverall capacitance of the RC circuit changes the frequency of the RCoscillator, thus, indicating deformation due to applied pressure to thesensor surfaces.

In some embodiments, the frequency of the RC oscillator is compared to areference value to determine if a change in frequency occurs; therefore,deformation due to applied pressure is detected. Accordingly, threealternatives are presented for performing the comparison between thereference value and the frequency of the RC oscillator. One alternativeis to define the reference value as a frequency equivalent to theoperating frequency of the RC oscillator when the applied pressure isnot excessive. In this instance, the reference value and the frequencyof the RC oscillator are both input into a frequency comparator, whereinthe frequency comparator evaluates if the values are similar; and thus,indicating one way or the other.

Optionally, the second alternative for comparison of the reference valueand the frequency of the RC oscillator comprises a frequency-to-voltageconverter, a DC voltage reference value, and a comparator, wherein thefrequency of the RC oscillator is input to the frequency-to-voltageconverter and a voltage corresponding to the frequency is output. Thecomparator compares the output voltage of the frequency-to-voltageconverter to the DC voltage reference value. The DC voltage referencevalue is equivalent to the output voltage of the frequency-to-voltageconverter when the applied pressure is not excessive. Accordingly, thecomparator outputs a signal consistent with whether the DC voltagereference value is similar to the output of the frequency-to-voltageconverter.

Optionally, the third alternative for comparison of the reference valueand the frequency of the RC oscillator is to directly measure thefrequency of the signal by counting the number of rising or fallingedges in a defined time period utilizing a device similar to amicrocontroller. In this manner, a baseline operating frequency may beestablished, and any deviation in frequency beyond a defined thresholdwill indicate the applied pressure is excessive.

In some embodiments, the voltage divider parallel plate capacitivesensor comprises at least two conductive sensor surfaces, which providesan analog input; an intermediary insulator; a reference voltage; ananalog-to-digital converter (A/DC); and a A/DC capacitor. The A/DC isinternally driven to the reference voltage such that the A/DC capacitoris fully charged, and the analog input of the conductive sensor surfacesis internally grounded such that the sensor surfaces are fullydischarged.
